Reactant (in a chem. equ.) | The left side, the individual elements |
Products (in a chem. equ.) | The combination of the reactants |
Coefficient (in a chem. equ.) | The # of a molecules |
Subscript (in a chem. equ.) | The amount of an atom in a compound |
Ionic Compound | a chemical compound in which ions are held together in a lattice structure by ionic bonds |
Covalent Compound | a compound in which the atoms that are bonded share electrons rather than transfer electrons from one to the other |
Metallic Compound | A metallic compound is a compound that contains one or more metal elements. |
Synthesis | purposeful execution of chemical reactions to get a product, or several products |
Decomposition | separation of a chemical compound into elements or simpler compounds |
Single Replacement | when an element or ion moves out of one compound and into another |
Double Replacement | two reactant ionic compounds exchange ions to form two new product compounds with the same ions. |
